Australia has developed a graphene-based filtration and desalination system

The water obtained at the outlet is suitable for drinking. Previously, engineers from the Massachusetts Institute of Technology proposed using graphene to create ultra-thin membranes for water filters. However, the proposal was not widely distributed due to the lack of technology for the mass production of graphene sheets. Scientists from Australia used the inventive process for making graphene sheets from soybean oil invented at CSIRO. This technology, called Graphair, allows you to produce cheap sheet graphene. For filtration and desalination of water, graphene sheets with channels of microscopic diameter comparable with the size of the molecules are used. Holes allow water to pass through, but retain salts and harmful impurities.

The experimenters used an ordinary filter coated with Graphair-developed film. A single purification turned out to be enough to turn seawater from the city bay into potable water. According to the developers, graphene-based filters do not lose efficiency during operation and purify water with a higher productivity than currently desalination plants. The proposed CSIRO technical solution to the problem of desalination and water purification will help get rid of complex and multi-stage plants that produced expensive drinking water. Now in the world the need for fresh water is constantly growing, the lack of clean drinking water annually leads to the death of millions of people. CSIRO plans to test Graphair technology in one of the countries suffering from drinking water shortages in 2019. In addition, scientists hope in the near future to find a company with the ability to begin mass production of graphene filters.
